LED Luminous Flux
The luminous flux of the mixed color output can be varied using the Requested Luminous Flux slider
located on the right side of the application window
produced by the LEDs varies, depending upon the chosen color. For example, a neutral white can
be set to a higher total flux than any of the three primary colors alone, as the color white is repre-
sented by a sum of the light output of each of the LEDs. The saturation point (the point of maximum
total flux) differs for different colors. Moving the slider to a requested flux higher than the saturation
point for a given color has no effect upon the light output of the LEDs as they remain at that mixed
color's saturation point. Note that this slider determines the requested luminous flux. This requested
value is usually derated by the color mixing firmware on the RGB unit. This is required to perform
temperature compensation, keeping the requested color as accurate as possible.

Dynamic Update
The RGB unit has two buttons that allow the board to be demonstrated without using the RGB unit
control application (see
turns the LEDs (alternately) on and off. The button labeled COLOR is used to cycle between seven
preset colors. At any time, the user can use the buttons on the unit to control the evaluation unit. The
application checks the current state of the RGB unit once every second and automatically updates to
accurately reflect the present state of the unit. If the user selects the Direct LED Control tab, the
LEDs on the RGB unit automatically turn off.
Shutting Down the Application
The application is closed by clicking on the Windows close box icon ‘x’ in the upper right corner of
the application window.
